  • Patent number: 11099949
    Abstract: A method and apparatus for programming a one-time programmable (OTP) memory device is disclosed that allows for resuming and recovering from an interrupted programming cycle (e.g. due to loss of power or user interaction). Upon re-initiation of a programming cycle with the same memory range, a programming controller may detect the memory address where interruption occurred, and resume programming from that address. If the programming interruption resulted in an incorrectly programmed word at the interrupted address, a word repair register may be mapped to the corrupted address to enable correction of that word. The remainder of the memory range may then be programmed normally.

  • Patent number: 10890939
    Abstract: A method for generating a not-yet (NYET) signal in a recovered reference system for recovering a device reference clock on a device, wherein the NYET signal indicates that the device is not yet ready for transition into a low power mode, in order to improve a quality of a recovered reference clock representative of a host reference clock of a host communicatively coupled to the device, may be provided. The method may include detecting receipt of start-of-frame markers from the host to the device, responsive to detecting receipt of the markers, determining whether a condition for NYET generation is being met, responsive to the condition for NYET generation being met, generating the NYET signal to cause the host to continue generating the markers, and responsive to the condition for NYET generation not being met, causing the device to generate an acknowledge signal for transition of the device into the low power mode.

  • Patent number: 10809758
    Abstract: A device may include an input for receiving information communicated from a host to the device and a controller configured to recover a device reference clock on the device, the device reference clock proportional to a host reference clock of the host, when clock signaling from the host to the device is unavailable. The controller may recover the device reference clock by measuring a ratio between the host reference clock and the device reference clock of the device by monitoring, with the device, host start-of-frame markers communicated from the host to the device via the input, creating a recovered reference clock based on the measured ratio, and creating local start-of-frame markers that are phase locked with the host start-of-frame markers based on the recovered reference clock.
